In this list (names retrieved from IPNI, 30 April 2011), the epithet formed after "Boccone" occurs in three variants: bocconei, bocconi, and bocconii. The first one is the genitive case of "Boccone", the second of "Bocconus", the third of "Bocconius", the latter two being latinized forms of "Boccone". The formation of epithets from personal names is regulated by Art. 60.7 and 60.11 and Rec. 60C of the ICBN (Vienna Code). The Code dictates that changes in spelling [of personal names] by authors who use intentional latinizations of personal names are to be preserved, except when they concern (a) only the termination of epithets, or (b) changes involving (1) omission of a final vowel or consonant, or (2) conversion of a final vowel to a different vowel, for which the final letter of the name is to be restored, unless the name already possesses a well-established latinized form, in which case it should be given its appropriate Latin genetive. Boccone lived well before Linnaeus and his name could have had a well-established latinized form. He rarely used the latinized form of his name however. In all of his books for example, even the ones in Latin, his name appears as "Paolo Boccone" on the title page. In the books in Latin, "Boccone" could have been a Latin case (Linnaeus seems to have treated it that way), but it would have been the ablative of "Bocco", not a derivative of a latinized form of "Boccone". In Hortus Cliffortianus (1738) and in Species Plantarum (1753), Linnaeus calls him "Bocco" (genetive: bocconis). From this it is obvious that Boccone's name does not possess a well-established latinized form, in which case the epithet should be formed in accordance with ICBN Rec. 60C.1(a): substantival epithets of personal names ending in a vowel are formed by adding the appropriate genetive inflection, which is "-i" in the case of a single male, and hence "bocconei" is the only proper form of the epithet. See ICBN (Vienna Code) Art. 60
